A watt of heat is the standard unit of measure of heat transfer and is defined as one joule of energy per second of time.
The formula to estimate the wattage (power) needed to heat a room is:
\[ W = L \cdot W \cdot H \cdot 1.25 \]
Where:
Let's say the length of the room (L) is 20 ft, the width of the room (W) is 15 ft, and the height of the room (H) is 10 ft. Using the formula:
\[ W = 20 \cdot 15 \cdot 10 \cdot 1.25 = 3750 \text{ Watts} \]
So, the wattage required to heat the room (W) is 3750 Watts.
